Our proposed relaxation approximation is a semilinear hyperbolic system without singularities. It yields a direction-depedent normal velocity at the leading term and captures, in the Chapman–Enskog expansion, the higher order curvature dependent corrections, including possible anisotropies.Physical Sciences and Mathematicsarticle
